I tracked this down to a very high frequency of GUI updates, when the 'Building data structures' progress bar is being updated.
With the attached patch, we still get many progress-bar updates and update-manager opens in now 5 seconds, rather than ~60s (or more with further power saving). ** Patch added: "Fix to address excessive progress bar updates causing issue" http://launchpadlibrarian.net/53085855/python-apt_0.7.96.1ubuntu4.debdiff ** Changed in: python-apt (Ubuntu) Status: New => Fix Committed -- update-manager cpu-bound for a long time opening https://bugs.launchpad.net/bugs/613743 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
